To all whom it may concern:

Be it known that I, Won'rrrrn a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Ventilators,of which the following is a specification.

This invention relates to ventilators and it has for its object the provision-of an im-' proved device of this character constructed in such manner as to effectually inject fresh air into a space to be v foul air-therefrom. It is oneof the objects of the invention to entilated or to eject [provide a ventilator of thecharacter indi-J' cated that will be extremely sensitivejin action, operable by-very light currentsiof and capable of rendering eflicientfservlce upon buildings thatflare surroundedby higher buildings.

It is a further object of the invention to provide a ventilatorconstructed 1n such manner that the passage of the wind later ally thereby will aid in drawing foul' a r from the structure to -which the ventilator is applied. 1 j v i It is a further object of the inventlon to 7 provide a ventilator adapted for use in. connectionwith cars or other movingvehicles, boats and the like.

It is another. ob'ect of theinvention to provide a ventilator constructed in such manner that it proof. 2 i i Further objects andadvantage's' of the invention' will be setforth. in the detailed description which now follows p ,7 In theaccompanying drawmgs;

Figure 1 is a vertical, sectional view'of a ventilator constructed in accordance with I the invention;

Fig. 2 is a horizontal, sectional View through the propelling hemispheres hereinafter described; and

Fig. 3 is a horizontal, sectional view through a centrifugal fan hereinafter de scribed.

Like numerals de'signate corresponding parts in all of'thefigu'res of the drawing. Referring to the drawing 5des1gnate's a tubular stem adapted to be connected to a structure to be ventilated, whether the latter be' a building, a car, avessel or otherwise. A. frame'secured to the stem 5 comprises the vertical portions 6 that rest against and are directly connected to the W. Molnar, I

will be thoroughly weather threaded stem 10 of a lower bearing holder 11 is screwed into the spider 9. This bearing holder carriesa glass bearing 12 which receives the lower endof a spindle 13 by which all of the rotative parts of the struc- 1 tureare carried. The lower end of the spin- I dle s pointed at 14'to' ada tit to engage" -w1th1n a correspondinglyshaped recess 15 of the glass bearing. The bearing 12 is held in position by screws 16, the inner ends of whlch' overlapf'the bearing. Tt'is manifest that by rotating the bearing holder 11 a vertical adjustment may be imparted to said bearing holder and consequently to the bearing. The: upperendof the spindle 18-ca'rprovided with afthreadedsteni- '21 that is .VENTILVATOR.

'75 1 riesfa spherical enlargement 17 that oper- I --'atesin an elongated recess 18 of an upper glass bearing 19." The bearing19 is mountfed in an upper bearing [holder 29 that is ries a lock nut 22, by'jmeansjof which the upperv bearing holder may be'bound in adjusted position. Screws-23 holdthe upper glass bearing 19in-position inthe holder 20. The spindle 13 carries a hemisphere hub '24: that is secured to thespindle a set 1 screw 25. Brackets 26 carry hollow hemi- J spheres 27 which serve as the propelling means for the stem13, s'aidhemispheres being secured'tothe brackets by rivets or'like fastening devices 28. -The brackets 26-are Q provided with threaded shanks 29 that are fscrewed into the hemisphere hub 2a and it is manifest that by screwing'the shanks into the hub toa greater or less degree-an accuspindle 13 may be effected. Furthermore,

ing the angle of thehemispheres. If the ventilator is being used'upon a building that rate balancing'of the hemispheres upon the is surrounded by higher buildings these hemispheres maybe adjusted to an upward angle "so that'they willbe engaged'and operated by downwardly directeddeflected currents'of air from the surrounding buildings.

Set screws 30'carried'by thehub 2 L serve to bind the sh'anks'29 against movementfafter the hemispheres have been adjusted to'the i desiredposition; 1 If desired small openings '27 may be "formed" in the hemispheres to "prevent them from retaining. rain-waterwhen adjusted to an upward inclination as outwardly. The centrifugal fan is disposed within a hemispherical weather-hood 36 that V is open at the bottom and is secured to the frame or yoke S by screws or like fastening devices 37. A wind flange 38encircles the upperend of stem 5 and, at, substantially, an angle of forty-five degrees- The func-' .tion of this wind flange is to; prevent wind from blowing upwardly into the weatherhood 36. An axially acting fan-.39 is mounted upon the spindle 13' below the centrifugal fan and preferably within the neck 5. I

The operation of the device is as follows: Assuming that the ventilator is to be used to eject foul air from the space to be ventilated the hemispheres 2T willbe-suitablyset to impart the desired direction of rotation to the spindle 13. This will intu-rn; impart rotationzto the centrifugal fan and to the to draw the foul air through tlie'stemt and terior of which is such as to deflect said air discharge thesame into theinterior of the centrifugal fan andthe'centrifugalfan will act to discharge this foul air laterallyiint'o the weather-hood 36, the shape'off the inhood'entirely weather tight, a. weather flange lOsismounted upon the top of the weather: I

hood and a weathercap tl ismounted upon thespindle 13 and extends downwardly over the. flange. This construction permits the free rotation of the spindle while maintaining the weather-hoodproof against the entry of; rain or snow.

By having the weather-hood extend'below the topof the stemfl5, this ste nisanotonly iistem 5, which aidsiin ejecting'foul air-from rendered effectually weather and storm proof but it provides a structure of such nao. 602

itureithat when the windsblow across the iniouth'oriunder side ofthe "weather hood' a vacuum :or isu-ctionis created :in the tubular fthe'biiilding. Thepi'ovisi on of the; glass i bearings provides a structure wherein the axiallyacting. fan 39. The fan 39 will act 1 a low hemispheres dis spindle may rotate without lubrication and substantially without friction. lhe sphericalenlargementup on the upper end ofthe spindle reduces friction to a minimum when the same engages the perpendicular inside surface of the bearing when revolving.

While I have shown-a fan. 39*upon-the spindle13 it is manifest that'the action of v the centrifugal fan alone would serve to draw air through the tubular stem 5 since, when. this fan throws the air contained therein outwardly into the weather-hood it tends to create a vacuuinfin the interiorof the centrifugal fan into which air would flow through the tubular stem 5.

lVhile l have referred tethe drawing of foul air through the stem it isv to'be understood that th1s term includes hot a r, fumes, gas, smoke, dust or any other flui'dthat'lt i may be desired to discharge from the space to be ventilated: j a
